That half life depends on concentration is not surprising to me; ethanol's half life in the blood also depends on it's concentration and the reason is rather straight forward: the liver has limited amounts of enzymes needed to process booze.
What is surprising to me, though, is that there is a mechanism that has such a massive effect at the extremely low concentrations of methane that are present in the atmosphere. Sure, OH is rare, but I'd guess is generated in large amounts in the upper atmosphere (UV + H2O -> OH- + O+ + momentum to keep them away from each other).
Does anyone here have any hard math on this?
For starters you don't (do you?) speak the original language, so you're at the mercy of the translator for the term "mark"
But, going more meta, most religious traditions don't have a strict textual interpretation of their texts. Certainly the author could not have known fingerprinting techniques 2000 years ago. It is not unreasonable to interpret "mark" to be an identifier.
Of course then the "fingerprint" mark would have to be compatible with the rest of Revelations.
And it's an excellent proxy since most people's consciences are formed by their religious beliefs (maybe not most HNers, but that's observational bias)
A cup of octane wouldn't be the worse thing you could swallow. Given a choice, I'll drink a cup of octane before a teaspoon of TEL (OP appears to favor cooking units)
That being said, there have been engines that run on diesel or gasoline. The M35 (deuce and half) has an engine that can run on just about any flammable material, preferably diesel. Gasoline's lack of lubrication will eventually kill it, but it'll run long enough to get you out of trouble.
